Audit and assurance alert: Revised CAS 540, auditing estimates

Published on: Mar 01, 2019

CPA Canada has issued this Audit and Assurance Alert: CAS 540, Auditing Accounting Estimates and Related Disclosures to raise awareness about the impact to all auditors resulting from changes to current CAS 540, regardless of the size or type of entity whose financial statements are being audited. These revisions are effective for audits of financial statements for periods beginning on or after December 15, 2019.

The International Auditing and Assurance Standards Board (IAASB) has prepared an At a Glance, which provides an overview of changes made to ISA 540 (Revised), Auditing Accounting Estimates and Related Disclosures and related conforming and consequential amendments. Since there are no Canadian amendments, revised CAS 540 mirrors ISA 540 (Revised). This alert contains a link to the IAASB At A Glance, which includes such topics as:

  • key enhancements to the standard
  • inherent risks factors
  • changes related to testing of accounting estimates
